    An example of patent absurdity.

    http://en.wikipedia.org/wiki/Asure_Software

    Asure (then called Forgent) collected $90 million from 30 companies for a patent they claimed on JPEG that the USPTO later ruled was not valid due to prior art. The patent covered the idea of using a single code to represent a run length followed by a second value (the RS codes used in JPEG).

    BTW, what had happened to the company which claim that it owns very similar to PAQ-ish algorithm (actually with wrong descriptions)? I just wonder.
